Most-reacted post we have seen: Revisiting the SpaceX Valuation: A Post-Prospectus Update! — 530 reactions on Jun 4, 2026.
In a post at the end of August 2026, I talked about interest rates in 2026 and marveled at the capacity of equities to keep rising in the face of rising rates. I argued that the resilience of stocks during the year could be traced to higher-than-expected earnings being reported by companies in 2026, and a concurrent increase in expected earnings in 2027 and 2028. Now that September 2026 is one for the record books, it is time to take stock and dig a little deeper, especially since the month brought about one of the largest increase in treasury yield rates in recent memory, and stock prices…
The war in Iran, oil prices and worries about a recession have all taken turns driving stock prices in 2026 but talk about interest rates and where they are going has been a constant concern all year. In the last few weeks, interest rate worries have come to the surface again, for three reasons, all related. The first is the rise in long-term US treasury rates to levels not seen in twenty years. The second is US debt exceeding $40 trillion for the first time , bringing attention to a long-standing worry that this debt burden may be hitting a tipping point for bond buyers. The third is a that…
It is undeniable technology companies have found their most hospitable setting in the United States and while there are many reasons for the US dominance of technology, easier access to capital for young businesses has been a key ingredient. Venture capital in the US, in its institutional and organized form, can trace its roots back to the 1950s, and over the last few decades, it has generated its share of legendary investors. Vinod Khosla is one of those legends, and it is for that reason that I was surprised to see him tweet the following: I understand that utterances on social media, often…
Foreword: I wrote and posted this piece on August 20, 2026, with the promise that I would listen to feedback and try to respond and incorporate ideas and suggestions. To keep this promise, I will edit this piece over time and reflect the changes I make. Original post: August 20, 2026 First update: August 21, 2026 - Updated AI TAM table to make explicit implications of AI market size for other businesses, employees and the economy. Second update: August 21, 2026 - Updated to incorporate impact of new businesses that may be born out of AI In a world where AI enters almost every conversation, it…
Earlier this year, I was asked what I thought about Leopold Aschenbrenner and I admitted that I knew little about him other than what I had read about him, more in social media, than in the press - that he was a 25-year-old wunderkind who had started at OpenAI but had left to start a hedge fund. That hedge fund, built entirely around a bet that AI would pay off big time and near term, buying companies in the AI orbit and selling short on the businesses (especially software) that AI would disrupt, had been able to raise billions of dollars from well-heeled and presumably sophisticated…
I am a lapsed academic, insofar as I have not submitted a paper for publication in more than two decades, but to acquire academic status, I did have to earn a PhD in the distant past. My doctoral dissertation , which like most doctoral theses is little noted and long forgotten, was completed in 1984 and focused on how the frequency of and delays in the release of information plays out in stock price volatility, skew and jumps. I don’t plan to rehash that paper, but there have been two long running news stories that reminded me of it. The first is a proposal being floated by the Securities…
